2020 Hyundai Palisade

The contact owns a 2020 Hyundai Palisade. The contact stated that while driving at an undisclosed speed, the sunroof glass fell off the track. The message that the sunroof was open was displayed. The local dealer was contacted, but the vehicle had not been diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 95,390.

I had just pulled into a (handicapped) parking space at my bank in Marana Az. as I prepared to stop with the brake still depressed, the car suddenly surged, with the tach going to 5000rpm. The vehicle jumped the sidewalk (with rear wheels making drag marks on the sidewalk. Vehicle shot up the slight rise , hit and demolished a concrete bench and some plants and was heading toward the main entrance when I shut the engine off with the ignition key. The car stopped less than 10 feet from the bank entrance. the car came close to going through the entrance shattering the glass doors and possibly injuring bank customers and employees. There was no warning, but this car has had 3 or 4 sudden engine surges before - about one every 1 1/2 years. Hyundai service has checked and denied any problems. On line queries indicate the surging problems are not uncommon. They happen without warning and result in serious injury and damage to people and property. Hyundai is stonewalling. Other drivers have similar events occur for sudden unintended acceleration (SUA) and suggest problems with the Electronic Throttle Control (ETC) including throttle position sensors. Our Palisade has less than 40,000 miles on it and has been well maintained, but Hyundai people refuse to acknowledge any problems - my wife and I consider that this car is a potential death machine.

The car is approximately 3.5 years old (2020) and the engine failed. The symptoms of the engine failure are the exact failures of all of the other Hyundai engines that failed over the last 10 years which were recalled. There needs to be further investigation in all of the engines Hyundai is putting out to protect people. Hyundai offered to pay 50% of this because they know they are wrong, but they need to pay 100% of customer issues.

While sitting at a stoplight with no moving passing traffic around my vehicle. There was a loud pop/crash sound that came from the roof. I pulled my car into a parking lot and found my sunroof had a large hole in the middle and was shattered. The glass is pushed upwards. My internal shade was closed, which kept glass from falling inside and on me. I was not hit by a foreign object, by all indications the glass spontaneously exploded.

The analog display on the vehicle does not coincide with the actual speed of the vehicle, which appears correct on the digital / numerical display. This issue happens regularly (i.e. daily) after first appearing on or about July 25, 2024, and does not appear to be accompanied by the use of any other specific component of the vehicle. There are numerous reports online where other owners are experiencing the same issue.

On Friday 6/28/24 I turned my vehicle on to drive to lunch. I put the vehicle in drive and started to move forward out of my parking spot when the following errors flashed on my dashboard in succession: "Check Forward Collision-Avoidance Assist System", "Check Lane Departure Warning (LDW) System", and "Check High Beam Assist System" and then the steering wheel locked while the vehicle was still moving forward. I put the vehicle in park, turned it off, turned it back on and there were no problems. On Saturday 6/29/24, the same series of events happened in the evening when turning the vehicle on from park. On Sunday 6/30/24 I turned the vehicle on in the morning and backed out of my driveway. When I put it in drive and started going down the road the same series of events happened again. This time, it did not resolved when I turned the vehicle off then back on, but happened 7-8 times in succession. The vehicle was not driven all day and when I turned it back on Sunday evening it seemed fine. I drove across town to meet a friend, put the vehicle in park to wait, then in drive (so it had been running for approx 30 minutes) and the issue happened again. On Monday 7/1/24 I had the vehicle towed to the dealership and the issue happened to the tow truck driver as he was getting the vehicle off of the truck. On Friday 7/5/24 I called the dealership and they have "verified my concern" but are not sure why it is happening. I am now waiting to hear back from them on this issue. I have read on an online forum that multiple people have had this same issue with the Palisade.
